Hi Allen & Karen
I must congratulate you on your Oz Glide product.
Having been in the Engineering & Automotive Heavy Equipment field for the past 49 years and I was impressed with the design & application of your product.
The use of the “Air Bag” to absorb the up and down movement and the use of the “Shock Absorbers” to inhibit the recoil forces has resulted with a very safe and smooth ride for Trailer or Caravan use.
I wish you the very best in your venture as the Oz Glide product is a good step forward to safer and smoother towing.
